I ended up at Alex and Pam's "wedding" through a referral from another bride. I put wedding in quotes because legally they were already married and this was basically the reception half of a wedding minus most of the activities. I told them I was very familiar with this idea because my own sister, who was married in Australia, did the exact same thing. Some people just aren't into putting their intimacy on display and I think that's just fine. No one needs to be bound by any matrimonial traditions they don't feel attached to. This means they had a really nice, really small backyard party with family and friends and it was a lovely intimate celebration that (luckily for me) they still wanted photographed.
